Documentation request

Up to now, I have been able to work out a lot of how to use GraphSCAD and how to create new nodes by looking at the examples, and by knowledge of OpenSCAD. But I'm sure it would help to have some documentation. When creating new nodes I blindly copy an existing similar node, but I would like to know how the GraphSCAD model works.
For instance, I note that some existing nodes have multiple output objects, yet only the one called, simply, 'object' gets displayed, assuming it is not connected to anything else. Is this correct? Is there anything else I should know?
Can 2D object nodes have more than one output?
Can a node have output of more than one type, such as a 3D and a 2D object?

A unconnected output plug named 'object' or 'object2d' will be displayed.

other unconnected objects will not be displayed. this avoid some 'inobject', 'outobject' to be displayed because they are not often connected.

You can output as many object or object2d in a node. And some other type of output plug... str etc...

There are now many nodes you can derivate from, but if you are coding some nodes and have problems, don't hesitate to PM me, i'll help U.

Thanks, I don't doubt that you will be most helpful. I'm very impressed at what you are producing.

will try to include more comments in node code
